Fantoccio!

Withered Bonnie is the heavily damaged, nightmarish version of the original Bonnie from Five Nights at Freddy's 2, known for his missing face (revealing wires and red eyes), missing arm, and tattered suit, implying he was cannibalized for parts for the Toy Animatronics. He's an aggressive antagonist, appearing in the Parts & Service room and moving through vents to ambush the player, requiring quick mask application in the left vent. His lore involves being possessed by a vengeful spirit, expressing bitter quotes about failure, and symbolizing the horror of abandoned, damaged animatronics.
